style="text-indent:25px">消音器實際上在解決燃氣噪音。典型消音器的原理，是在內(nèi)部設置多個碗型結構，讓出膛高溫燃氣在每一個碗型結構形成的密閉空腔內(nèi)逐級膨脹釋放能量，并因此在較終出消音器口時明顯降低速度和能量，因此達到降低燃氣出膛噪音的效果。發(fā)射的主要噪音來源，從大到小排列。高壓燃氣出膛時膨脹產(chǎn)生的噪音和超音速燃氣產(chǎn)生的激波聲，在沒有加消音器的時候，平常聽到的聲主要都是來自這個來源，甚至說全部來自它，因為這個聲音是遠大于其他兩個來源的。我們后文簡稱這一來源為燃氣噪音。如果發(fā)射的是超音速彈，彈丸出膛后空氣中超音速飛行產(chǎn)生的激波噪音。相對個來源，這個聲音較小，但音量也很大，而且音色很尖銳。后文簡稱為激波噪音。擊發(fā)和機循環(huán)完成拋殼上膛本身伴隨著金屬部件之間的碰撞，這個聲音又明顯小于前兩者，但也不可忽略。后文簡稱為機噪音。微穿孔消聲器不使用任何阻性吸聲填料，采用微穿小孔多空腔結構逐級改變原氣流的聲頻。</p><div
